定义一个分数类,实现各个成员参数并在主函数中测试

#include#includeusingnamespacestd;classComplex{floatm_Real;floatm_Image;public:Complex(floatr=0.0,fl

classscore{privatedoubleenglish;publicvoidsetScore(doubleenglish){this.english=english;}publicvoidpr

//main函数里能输入两个复数.已经用VC++6.0编译通过了...希望对你有帮助#include#includeclassComplex{private:floatreal;floatimagin

#include#includeusingstd::cout;usingstd::cin;usingstd::endl;usingstd::string;classBook{public:Book(s

classRecangle{private:intwidth;intlength;public:Recangle(){width=0;length=0;};Recangle(intw,inth){wi

easy~#include#includeusingnamespacestd;classComplex{private:doublereal;doubleimage;public:Complex(do

以下程序,直接拿去交作业吧,都测试过了.//圆周长面积#include#definepi3.14159classcircle{public:voidsetRadius(){std::cout

classTriangle{private:\x05doublea;\x05doubleb;\x05doublec;public:\x05Triangle():a(0),b(0),c(0){}\x05

#ifndefFRACTION_H_#defineFRACTION_H_#includeintgcd(intm1,intm2);classFraction{public:\x05Fraction(){

classComplex{public:Complex(){real=0;imag=0;}//定义结构函数Complex(doubler,doublei){real=r;imag=i;}//构造函数重

把这三个类分别放到三个.java文件中,然后编译运行即可.publicclassCircle{privatedoubler;publicCircle(doubler){this.r=r;}public

#includeusingnamespacestd;classcomplex{public:complex():real(0),vir(0){}complex(floata,floatb):real(

classCat{privateintnumofcats;publicintgetnumofcats(){returnnumofcats;}}

classDate{intyear;intmonth;intdate;publicDate(intyear,intmonth,intdate){this.month=month;this.year=y

usingSystem;classRectangle{privateintwidth;privateintheight;publicRectangle(intw,inth){width=w;heigh

//这是我博客上的分数类例子,重载了+-*/以及#includeusingnamespacestd;classfenshu{intfenzi;intfenmu;public:friendostream

#include#includeusingnamespacestd;classData{public:\x09Data(stringName):name(Name){}\x09virtualvoidp

看书运算符重载,拷贝构造及赋值为私有

“抽象函数”和“没有实现的函数”并没有因果关系再问：不是抽象类必须有一个纯虚函数吗？纯虚函数不是无函数体定义的函数吗？再答：虽然违反直觉，不过纯虚函数是可以有定义的。
